Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 12, 2021The c.1663G>A (p.G555S) alteration is located in exon 5 (coding exon 3) of the C17orf80 gene. This alteration results from a G to A substitution at nucleotide position 1663, causing the glycine (G) at amino acid position 555 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
